Answer:
 The slope of the line 

The point ( x₁ ,y₁) = ( 2,1)
Explanation:
Explanation:-
Given that the line 
 

Comparing y- y₁ = m(x-x₁)
 The slope of the line 

The point ( x₁ ,y₁) = ( 2,1)
The equation of the straight line
 

 2(y-1) = -(x-2)
 2y -2 = -x +2
 x + 2y -2-2=0
 x +2y -4=0
Final answer:-
The equation of the straight line x+ 2y-4=0
 The slope of the line 

The point ( x₁ ,y₁) = ( 2,1)
